The very popular show "Lip Sync Battle" first got its start as a game on "The Tonight Show Starring Jimmy Fallon," but the host used a different lip-synch formula Monday night when Ariana Grande stopped by.
Fallon debuted "Lip Sync Conversation" last night. As he went to check up on Grande in her dressing room, instead of having a regular conversation, the two spoke to each other almost entirely through popular songs. Fallon opened up the conversation with the lyric's to G-Eazy's "Me, Myself & I" and Grande replied using 4 Non Blondes' "What's Up."
"Why you gotta be so rude?" Grande later asked the host, using the band Magic's lyrics.
"I'm not trying to be rude," Fallon replied with R. Kelly's voice from the song "Ignition."
The conversation also included discussions about their throwback Thursday Instagrams and their upcoming plans for the weekend, including songs from Frank Sinatra ("It Was a Very Good Year"), Rihanna ("Work"), Sia ("Chandelier") and Justin Bieber's ("Sorry"). Fallon even had time to sneak in Grande's latest single, "Dangerous Woman." The newest song that the duo used was "Sandcastles" from Beyoncé's new visual album, "Lemonade," which premiered on HBO over the weekend.
After their "Lip Sync Conversation," Grande stuck around to chat with Fallon. She brought out her dog Toulouse, who can wink, and also embarrassed her grandmother. The 22-year-old pop star's "Nonna," who is a huge fan of Fallon's, was in the audience (along with her mother and older brother Frankie). Before Grande went on "The Tonight Show," she tweeted that Nonna said Fallon was the only man that she would stay up past 11:30 p.m. for.
"When I told her I was going to take her here to meet you, she was like, 'I gotta start planning my outfit,' and I was like, 'Nonna what do you think is going to come from this?' And she goes, 'You never know, I'm very naughty,'" Grande shared.
After Grande embarrassed her grandma, it was time to move on to her mother. Fallon then played a clip of Grande's mom freaking out after the singer played her upcoming album for her for the first time.
Grande's new album, "Dangerous Woman," is due out May 20.
